Once the data is stored in the IotHub it can remain there for max 7 days. As long the data is in the hub it can be read by various readers. Commonly data is read by using Azure Stream Analytics. However, sometimes it is required to implement a native reader. There are two approaches when reading events...

To send telemetry data from device, we will use Microsoft.Azure.Devices.Client or generally one of following two packages: First one is used when programming devices on a full desktop (typically simulators). If your device is running on UWP you will use the PCL package. Before we send telemetry data...

Last week we organized IoT hackathone (+ workshop) with Intel. The idea was to show how to build real-life IoT solution on Intel’s Edison Board connected to Azure Event Hub. We created a simple Node.js application running on Edison board, by using Intel’s XDK IoT Edition . The full tutorial, which...

Stream Analytics is probably one of consisted parts of a typical IoT solution. When huge number of devices produce telemetry data, some component will have to analyze them. In a typical IoT solution the reference architecture considers almost always ingest of data in some kind of temporary storage. AT...

When working with IoTHub, you might get following exception: An exception of type 'Microsoft.Azure.Devices.Client.Exceptions.DeviceMaximumQueueDepthExceededException' occurred in mscorlib.dll but was not handled in user code Additional information: Total number of messages on IotHub 'daenethub'...

When working with Azure Service Bus and AMQP protocol, you will find in the official documentation that outgoing port 5672 is required. This is true, but missing part in documentation is port 5671. So, if you use AMQP you will have to open outgoing ports 5672 and 5671 on TCP protocol.

Windows 10 IoT Core is a kind Windows Operative system, which is some incarnation of Windows 10. It enables us to develop .NET and Windows applications, by using common Visual Studio toolset. Even more interesting is a fact that Windows 10 IoT Core can run on PI2 ( Raspberry ). This enables us to build...

The Durable Task Framework is an open source project originally started by Microsoft. It enables you to write orchestrations in pure C# using the .Net framework. By using of this framework, you can implement many kinds of integration projects without of need to use any Enterprise Service Bus product...

When implementing services, you will at least on Windows typically implement the service und run it in Service Control Manager (SCM). Another option would be implement a job, which will be scheduled by System Task Scheduler, which is built in the operative system. However if the program has to run for...
